not having long hair in TES and ME actualy makes sense though. Long hair is very distinct disadvantage when in combat, most armies both past and present made so that you either had no hair, short hair, or if you had long hair you would put in a bun. Long hair can and offen goes by the rule of cool, but then sometimes the rule of practicallity trumps it
If long hair was such a problem when fighting in ancient times most of the nations would have died out - haircuts are a modern invention you know... ME and TES are two very different things - hair in the face when you are shooting, and in a world where haircuts are a norm is one thing, long hair in pseudo historical environment - completely different, you don't need a perfect aim to hit someone with a sword
Oh, and additionally - medium length hair - that is over the shoulder, but longish is the one that gets in the face the most, the actual long hair are to heavy to float around, and don't get blown in your face. I had both cuts, and waist long hair get in the way far less than a bob cut.
